Researchers from Spain have identified microplastics in human reproductive fluids, specifically in semen and follicular fluid within the ovaries. These findings add to the growing evidence of microplastic contamination in human tissues, which already includes seas, drinking water, and food. The most commonly detected polymer was polytetrafluoroethylene (PTFE). While the presence of microplastics in these reproductive fluids is confirmed, the potential impact on sperm, oocytes, and fertility remains unclear and is currently under investigation. The discovery raises concerns about possible implications for reproductive health and fertility, as follicular fluid plays a critical role in the development of the ovum. This research highlights an emerging environmental and health issue that scientists are continuing to explore.
